“The inflated ego of the tyrant is a curse to himself and his world—no matter how his affairs may seem to prosper. Self-terrorized, fear-haunted, alert at every hand to meet and battle back the anticipated aggressions of his environment, which are primarily the reflections of the uncontrollable impulses to acquisition within himself, the giant of self-achieved independence is the world’s messenger of disaster, even though, in his mind, he may entertain himself with humane intentions. Wherever he sets his hand there is a cry (if not from the housetops, then—more miserably—within every heart).” – Joseph Campbell, The Hero with a Thousand Faces
